Towords — Help Your Child Truly Remember Words Towords solves the real challenges of word learning — spelling, listening, speaking — so kids build a rock-solid command of English vocabulary. Founded in 2010, Towords is China's original vocabulary app and an official App Store recommendation. Grounded in linguistics, psychology, and brain science, we pioneered the "Deliberate Acquisition Model" — deliberate practice plus natural immersion. Our graded K-12 word system lets kids progress well beyond textbooks, at their own pace. A rich reward system — scholarships, badges, study buddies, snail shells — keeps kids motivated and eager to learn. No nagging. Every child also gets a dedicated teacher for one-on-one guidance, focused on one goal: making words stick. Our promise: if it doesn't work, cancel anytime for a full refund. Words Aren't Meant to Be Rote-Memorized English is a living language, not a static subject. Fluency comes from a continuous loop of input, reflection, and output — until understanding and expression click. Rote memorization is the hard path few finish. Deliberate acquisition is the smooth highway: sound method plus consistent effort. Graded Word System for K-12 Just 15 minutes a day adds up remarkably. Start in Grade 3, stay consistent, and by high school your child will have a 10,000+ word vocabulary — well beyond Chinese exam requirements, on par with TOEFL 90+ or IELTS 6.5. Level 1 — Starting Out: Current semester textbook words. Phonics + examples. 0–100 words. Level 2 — Taking the Lead: K-12 national curriculum (A1). Phonics + examples. 100–1,500 words. Level 3 — Switching Lanes: Core KET vocabulary (A2). Phonics + examples. 1,500–2,000 words. Level 4 — Leap Forward: Core PET vocabulary (B1). Phonics phases out; training shifts to definition-based learning — start thinking in English, enter the native-like "learning English through English" state. Level 5 and beyond… Explore the full curriculum in the app. Phonics Training Core training in Levels 1–3. Through listen → repeat → spell → verify, kids build phonics skills that unlock reading and spelling independently. Once phonics clicks, they can spell a new word from hearing it, or read it aloud from seeing it. Example Sentence Training Supporting training in Levels 1–3. Sentences give words real context. Kids deepen their understanding while building listening and speaking foundations — with direct gains on reading and comprehension exams. Definition-Based Training Starting at Level 4 (PET), this becomes the core. Kids read and listen to English definitions, internalize meaning, recall the word, then spell it out. It's our most powerful training — a pivotal leap into native-like English thinking. …More inside the app. Massive Word Library Textbook words: Virtually every elementary, middle, high, and international school textbook. Exam words: Starters, Cambridge Main Suite, TOEFL Junior, Linguaskill, TOEFL, IELTS — virtually every major exam. Custom word lists: Build your own books tailored to your child's needs. Trusted, Authorized Content Every definition and example comes from the officially licensed Collins COBUILD Advanced Learner's Dictionary — professionally sourced and reliable.
